BMW Motorcycle Fuel Tanks

Motorcycle Gas Tank Buying Guide

The Kinds Available

There are several, and they come in all shapes, sizes, and capacities. Some brands manufacture narrow, high-tunnel, and low-tunnel types, while others offer everything from bobbed and stretched to prism, coffin, and dished.

What They're Made of

Generally, one of three materials: steel (in the case of most bikes), which is exceptionally durable and weldable; plastic, which is lightweight, doesn't rust, and is low-noise; or, more rarely, fiberglass. Depending on the kind, it may even have an internal coating to stave off corrosion.

The Parts of One and What They Do

• The liner: seals the tank, safeguards against deterioration
• The line: joins the tank to the engine and shunts gas to and from it
• The filter: prevents infiltrates from getting into the engine
• The cap: closes off the tank from the outside after you add or remove fuel
• The petcock: a valve, which controls the flow of gas; some have on, off, and reserve settings, while others run automatically

Signs it's Time to Replace One

• If it's dented and you can't just pop out the dent, put on fresh body filler or another patch, and repaint
• If it's leaking and you can't weld or braze it
• If you're building a custom bike and need a higher capacity (absent being able to put on an auxiliary or reserve fuel tank)
• If you want to add a touch of personal style

In such cases, a new fuel tank is easy to install: most bolt on, and few need any extra welding or fabrication. If you are putting in a new one, however, be sure it's the genuine OEM article. BMW designs them specifically for its motorbike lines, after all, which means a guaranteed fit and finish.
